I'm not positive but I will try to help

The first pic, the 2 black boxes, one is the Express Down Window Module, it makes your drivers window go down when you hit the switch. The second is the Chime Module.

2nd pic looks like the Keyless Entry Receiver, is that mounted on the right side, behind the kick panel?

3rd pic, these go to your turn signal switch, everything in the sterring column goes thru these 2 connectors

Last pic, brake light switch, the top switch i think is the Cruise Control Disconnect Switch

The chime module is what makes noise when the key is in the ignition. I might be wrong about one of the black boxes being the chime module, it might be the high blower relay, not sure but I will try to find out.

I already removed one black box that said "TRW" on it which I assume was for keyless entry. I think the box with the teal connector is the VATS stuff.

I need to know if both those connectors under the steering shaft are for. Is one for airbags? Mine are gone so if so I need it gone too.

airbag connector is yellow and marked. 1st pic 4 wire connector is going to express down module but the other thing may be the RAP (retained accessory power) module. been awhile since i've seen one. it sits on the firewall towards the driver side over the tranny hump. if you can get part numbers i can probably identify all of them. i agree with the other things that csjta2 said

You guys were correct. Just removed the RAP and express down modules and re-wired the power windows.

Fuse 16 - crank - 3a I have yellow ign wire going to the fuse box and a ppl wire exiting - where does the ppl wire go? Looks like i've had it disconnect for a while now.

If anyone needs the keyless entry box, RAP box, or express down box, let me know.

And no starting issues huh? SO far I pulled out the entire harness down the right side(rear speakers, factory amp, power ant.) and the entire console harness(cig light, acsy power, brake switch, airbag sens, ash light). Now I want to start pulling the dash wires out but that stuff makes me nervous when I dont know exactly what they are.

None at all. Traced every wire to its source before chopping it out.
